Algebra 1 Applications of Percents

Dr. Eaton will cover Applications of Percents with examples of real life situations. You will learn about percentage of increase which is illustrated with sales tax, as well as percentage of decrease which can be understood as a discount.

A suit was originally $160, but is discounted 30% . A sales tax of 7.5% is added, based on the discounted price. What is the final price of the suit? To the nearest percent, what is the percent of change between the original price and the final price paid, including sales tax?

A camera was originally $225, but is discounted 15% . A sales tax of 7.5% is added, based on the discounted price. What is the final price of the camera? To the nearest percent, what is the percent of change between the original price and the final price paid, including sales tax?

*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
